Hi,
I've linked avifile library version 0.6 into my project, and am getting
memory leaks reported by mpatrol at the following locations. Could you
please
let me know if these are known-leaks, and if they are being looked at?
MEMORY LEAK 1
========================================
0x080C72DC (8 bytes) {operator new[]:200:0}
[1024|__10LDT_Keeper|/avifile-0.6/lib/common/ldt_keeper.cpp|198]
0x400FD2A1 __10LDT_Keeper+225 at
/avifile-0.6/lib/common/ldt_keeper.cpp:198
0x400FD347 __static_initialization_and_destruction_0+55 at
/avifile-0.6/lib/common/ldt_keeper.cpp:208
0x400FD392 __static_initialization_and_destruction_0+130 at
/avifile-0.6/lib/common/ldt_keeper.cpp:208
0x400FDFA5 __do_global_ctors_aux+49
0x4000DAC2 _dl_init+306 at
/export/home/chmou/rpm/BUILD/glibc-2.2.2/elf/dl-init.c:70
0x40001DF1 _dl_start_user+58
This means there is a leak in ldt_keeper.cpp at line 198 of 8 bytes
prev_struct=new char[8];
*(void**)array.base_addr=prev_struct;
close(fd);
}
The above are lines 198,199,200
MEMORY LEAK 2
=====================================================
0x081D5650 (20 bytes) {realloc:251:0} [1024|RegisterComClass|
/avifile-0.6/plugins/libwin32/loader/win32.c|2098]
0x40067778 RegisterComClass+88 at

/export/home/chmou/rpm/BUILD/glibc-2.2.2/elf/dl-init.c:70
0x40001DF1 _dl_start_user+58
This means there is a leak of 20 bytes at win32.c line 2098
Line 2098 is the realloc line from below:
static struct COM_OBJECT_INFO* com_object_table=0;
static int com_object_size=0;
int RegisterComClass(GUID* clsid, GETCLASSOBJECT gcs)
{
if(!clsid)return -1;
if(!gcs)return -1;
com_object_table=realloc(com_object_table, sizeof(struct
COM_OBJECT_INFO)*(++com_object_size));
com_object_table[com_object_size-1].clsid=*clsid;
com_object_table[com_object_size-1].GetClassObject=gcs;
return 0;
}
